Description

Technical Field

[0001] This invention relates to the field of tilting and lifting devices, and particularly to a tilting and lifting device for an aerated concrete production line. Background Technology

[0002] Autoclaved aerated concrete (AAC) blocks are a new type of building material that is lightweight, porous, has good thermal insulation, fire resistance, can be nailed, sawed, and planed, and possesses a certain degree of earthquake resistance. The production process of AAC blocks mainly includes steps such as batching, mixing, pouring, pre-curing, cutting, autoclaving, and maintenance. During the production process, the AAC blocks need to be flipped and demolded. In existing flipping and lifting equipment, a flipping mechanism is used to lift the mold box and flip it 90° before placing it sideways on a cutting trolley. After the mold box is placed sideways on the cutting trolley, a clamping arm mechanism is used to drive the locking arm on the mold box to rotate and open it for demolding. However, the existing clamping arm mechanism has two clamping arms, each requiring a corresponding push-pull cylinder and rotating rod to drive its rotation, resulting in a complex structure. Summary of the Invention

[0003] The purpose of this invention is to provide a tilting hoist for an aerated concrete production line, thereby overcoming the shortcomings of existing clamping arm mechanisms that require corresponding push-pull cylinders and rotating rods for each clamping arm to drive rotation, resulting in a complex structure.

Detailed Implementation

[0026] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0027] Figures 1 to 8A schematic diagram of a tilting hoist for an aerated concrete production line according to a preferred embodiment of the present invention is shown. The tilting hoist includes a gantry frame 2, a sliding column 3, a lifting beam assembly 4, a tilting mechanism, and a clamping arm mechanism. The gantry frame 2 is movably mounted on a support frame in the factory, facilitating its movement for lifting and transporting the mold boxes.

[0028] refer to Figures 1 to 8 The overhead crane frame 2 has two symmetrical sliding columns 3, the upper ends of which are connected to the overhead crane frame 2. A lifting beam assembly 4 is horizontally installed between the two sliding columns 3, allowing it to slide up and down, and is driven by a drive mechanism. Below the lifting beam assembly 4 are two symmetrically arranged flipping mechanisms for flipping the mold box. A clamping arm mechanism is installed on the lifting beam assembly 4 and located above the two flipping mechanisms. The clamping arm mechanism includes two clamping arms 7, a first rotating rod 8, a second rotating rod 11, a push-pull rod 6, and a push-pull cylinder 14. The two clamping arms 7 are symmetrically arranged, and the fixed end of each clamping arm 7 is rotatably connected to the lifting beam assembly 4 via a rotating shaft. Each clamping arm 7 corresponds one-to-one with a locking arm on the mold box. Each clamping arm 7 has a rotating elongated hole 5 on its movable end, which corresponds to and connects to a locking arm on the mold box, driving the locking arm to rotate and open, facilitating subsequent demolding operations. The clamping arm 7 on the left is the first clamping arm, and the clamping arm 7 on the right is the second clamping arm. The middle part of the first rotating rod 8 is connected to the pivot of the first clamping arm, the front end of the first rotating rod 8 is hinged to the left end of the push-pull rod 6, the right end of the push-pull rod 6 is hinged to the rear end of the second rotating rod 11, and the front end of the second rotating rod 11 is connected to the pivot of the second clamping arm. The right end of the push-pull cylinder 14 is hinged to the lifting beam assembly 4, and the left end of the push-pull cylinder 14 is hinged to the rear end of the first rotating rod 8. By driving the push-pull cylinder 14 to extend or retract, the first rotating rod 8 can be driven to rotate, thereby driving the first clamping arm to rotate. At the same time, the rotation of the first rotating rod 8 synchronously drives the push-pull rod 6 to move, thereby driving the second rotating rod 11 to rotate, and then driving the second clamping arm to rotate. The rotation direction of the second clamping arm is opposite to the rotation direction of the first clamping arm. Therefore, by simply driving one push-pull cylinder 14 to extend or retract, two rotating rods and push-pull rods 6 can drive two clamping arms 7 to rotate synchronously in opposite directions, thereby driving the locking arm on the mold box to rotate and open for demolding. The structure is simple and the operation is convenient.

A flipping mechanism is provided at the lower end of each vertical beam 401 to facilitate lifting and flipping the mold box 90°. The horizontal beam 402 is installed laterally between the two vertical beams 401, and a clamping arm mechanism is installed on the horizontal beam 402, so that the lifting beam assembly 4 has an H-shape, which is structurally stable, easy to install, and facilitates the layout and installation of the flipping mechanism and the clamping arm mechanism.

Two limiting rods 15 are provided on the crossbeam 402 of the lifting beam assembly 4, which are symmetrically arranged on the left and right and located behind the clamping arm mechanism. Each limiting rod 15 is inclined downward from front to back to limit the angle of the flipping mechanism to flip the mold box, so that the mold box can be kept flipped 90°.

[0032] refer to Figure 2 and Figure 3 Preferably, the tilting device further includes a synchronous shaft 16, which is laterally arranged between the two sliding columns 3. The synchronous shaft 16 is rotatably connected to the crossbeam 402 of the lifting beam assembly 4. Each sliding column 3 is provided with a synchronous rack 13 for upper and lower guidance on its rear side. The synchronous shaft 16 is provided with a synchronous gear 12 at the position corresponding to each synchronous rack 13, which meshes with the synchronous rack 13, so as to realize the synchronous lifting of the entire lifting beam assembly 4.

[0033] refer to Figure 5 Preferably, each clamping arm 7 is L-shaped so that the rotating elongated hole 5 on the clamping arm 7 can be engaged with the locking arm on the mold box.

[0034] refer to Figure 8 Preferably, each sliding column 3 is provided with a reinforcing frame, which includes a reinforcing rod 18 and a U-shaped frame 17. The reinforcing rod 18 is connected to the outer side of the sliding column 3, and the U-shaped frame 17 is connected to the reinforcing rod 18, with the opening of the U-shaped frame 17 facing upwards. During installation, the upper ends of the sliding column 3, the upper ends of the reinforcing rod 18, and the upper ends of the U-shaped frame 17 can all be connected to the crane frame 2 to improve the strength of the sliding column 3 and the stability of the installation.

[0035] refer to Figures 1 to 4The tilting mechanism of the tilting lifting device of the present invention includes a tilting plate 9 and a tilting cylinder 10. The middle part of the tilting plate 9 is rotatably connected to the lower end of the vertical beam 401. The tilting plate 9 is provided with two bayonets that correspond to two pins on the side wall of the mold box. By connecting the bayonets to the corresponding pins, the mold box can be lifted. The lower end of the tilting cylinder 10 is hinged to one end of the tilting plate 9, and the upper end of the tilting cylinder 10 is hinged to the vertical beam 401. After the mold box is lifted, by driving the tilting cylinder 10 to extend or retract, the tilting plate 9 can be rotated, thereby causing the mold box to tilt by 90°.
